UNITED STATES PATENT 'OEEIcE` JOHN G. ROGERS, OF WILLIAMSBURG, OHIO,ASSIGNOR TO VOLNEY STOOKTON, OF SAME PLACE.

IMPROVEMENT IN TIRE-HEATING FURNACES.

Specification forming part of Letters Patent No. 143,465, dated October7, l83 application iiled May 1, 1873.

To all whom it may concern:

Be it known that I, JOHN G. RoGEns, of Williamsburg, in the county ofClermont and State of Ohio, have invented a Tire-Heating Furnace, ofwhich the following is a specification:

The object of my invention is to conveniently, evenly, and rapidlyheatwagon-tire, and analogous articles, by combining with an annular furnacea circular pipe or tuyere having discharge-nozzles, connecting with theinterior of the bottom of said furnace, through which a blast of air isto be conducted to support combustion in the furnace.

The accompanying drawing forms a part of this specification, and shows,in Figure l, a top view of a device embodying my invention. Fig. 2 showsa vertical transverse section of the same, in whichf- A represents theannular furnace. This furnace is made of iron, of any convenient size,and may be lined with brick, and is provided with a tight-tting cover,suitably hinged to the furnace. B represents a circular tuyere. Thistuyere has a receiving-nozzle, C, and several discharge-nozzles, a a a.These dischargenozzles convey air om the tuyere to the fuelchamber inthe furnace. D represents ribs.

These ribs are attached to the bottom of the furnace, equidistant apart,and are sufficiently high to support the tire and leave sufficient spacefor fuel between the tire and bottom of the annular furnace. Erepresents a flue for carrying off the smoke. Any suitable blower may beattached to the receiving-nozzle O.

` To operate this device, the fuel-chamber is filled with fuel, when thetire to be heated may be laid on the ribs D and upon each other in largequantities, and all evenly and rapidly heated.

I am aware that annular furnaces are used; but these have only a naturaldraft, which is not sufficient to secure the greatest advantages of timeand fuel; hence I supply an artificial draft through the agency of thetuyere B and any suitable blower. i

It is deemed not necessary to show the blower in the drawing, as acommon device may be used for that purpose.

What I claim is- The combination of the annular furnace A,

having the hinged cover, ribslD, and smoke-` iiue E, with the circulartuyere B, having receivingnozzle C and discharge-nozzles et a a, and anysuitable blower, as and for the purposes-set forth.
